In a rare show of unity, North Korea’s Kim Jong-un, Russia’s Vladimir Putin, and China’s Xi Jinping appeared together at a grand military parade in Beijing on Wednesday.

The leaders walked side by side on the red carpet, marking the 80th anniversary of the end of World War II. This was Kim’s second overseas trip in six years, and the first time he joined both Xi and Putin at the same event. His daughter, Kim Ju-ae, was also present.

Iranian President Masoud Pezeshkian and Myanmar’s military chief Min Aung Hlaing attended as well.

In his speech, Xi said humanity faces a choice between “peace or war, dialogue or confrontation, shared prosperity or mutual destruction.” He stressed that “China cannot be stopped” and called for eradicating the roots of war.

Former U.S. President Donald Trump reacted online, writing: “Best wishes to President Xi and the great people of China. Please also extend my warm regards to Vladimir Putin and Kim Jong-un when you conspire against the United States.”
